Re: [CAD_CAM_EDM_DRO] Handwheels again?!? was Re: true closed loop vs. hobby closed loop

Yeah:
Especially when they slap you in the gonads at a couple of hundred RPM.
Trying to use a handwheel equipped CNC for manual milling is a real pain.
For safety reasons, most manufacturers either spring load them to be
normally disengaged, or they make the handles fold and spring load them to
be normally folded in.
It is unbelievably annoying to try to mill something with this arrangement.
Every time you want to grab a handwheel, it's either ineffective or not
where you put your hand.
That breaks the rhythm of your work so badly that it's almost impossible to
be productive.
I'm with Ballendo on this one!!.
Cheers
